SEWI FOR SEVVED ARTICLES.

SPECIFICATION forming part of Letters Patent No. 718,943, dated January2C, 1903.

Application iiled February 18,1902. Serial No. 94,577. (No model.)

To all whom t may cm2/cern:

Be it known that I, EDWARD T. ALLAN, a citizen of the United States,residing at Cincinnati, in the county of I-Iamilton, State of 5 Ohio,have invented certain new and useful Improvements in Scams for SewedArticles,Y of which the following is a description, reference being hadto the accompanying drawings and to the letters of reference marked lothereon.

My invention relates to an improvement in seams for sewed articles; andits object is to provide a novel bound seam for use on cloaks and thelike in which two pieces of fabric are united and their raw edges boundall in one operation and by a single line of stitches.

The invention consists in the matters hereinafter described, andreferred to in the appended claims.

In the accompanying drawings, which illustrate the invention, Figure lisa crosssection of the seam after its completion, but before itis pressedor iiattened out. Fig. 2 is a similar view showing it in process ofbeing pressed or flattened. Fig. 3 is a similar View showing it after ithas been pressed or flattened out; and Fig. 4: is a view similar to Fig.l, illustrating the mechanism-t'. e., folder and needlefor making theseam.

In the drawings, A A represent, respectively,npper and lower pieces offabrics whose edges are superposed.

B is a binding-strip, which is herein shown in Figs. l, 2, and e asfolded around the raw edges of the two pieces of fabric and having a hemfold a on each edge. The binding-strip B is provided with a central foldor crease I), which projects inwardly between the two edges of thematerial, keeping them sepa- 40 rated. The parts of the seam are heldtogether by a single line of stitching c passing through both edges orhem folds of the binding-strip and through the two pieces of fabric, butnot through the apex of the central fold or crease IJ of thebinding-strip. It will be seen that by this arrangement when the seam iscompleted and ready to be ironed or otherwise pressed flat the centralfold or crease in the binding-strip acts to separate 5o the two edges,so that they will not fold over wardly only so far as to properlyseparate the two pieces of fabric A A', and not so far as to cause thecentral fold or crease of the binding-strip to be engaged bythe needle din its descent.

Other apparatus may be used for making the seam; but the above is simplymentioned as a convenient arrangement which has been devised for thispurpose, and it will be understood that so long as the raw edges of thefabrics A A' are properly separated, so that in pressing the seam flatthey will not fold in the same direction, but will turn in oppositedirections, it may not be absolutely neoessary to form the centralcrease or fold I) in the binding-strip, it being sufcient, so long asthe above result is accomplished, that the folding-guide accommodate agreater width of strip than is represented by the mere distance betweenits upper and lower edges and to make the binding-strip entirely coverthe edges of the pieces of fabric to fold around said edges and to besecured by the line of stitching c.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

l. The herein-described seam for sewed articles, comprising fabricshaving inwardly oppositely turned portions, and a binding-strip coveringthe upper faces, the edges and the lower faces of said inwardly-turnedportions, and a line of stitching passing through the inner edges of thebinding-strip and the two pieces of fabric; substantially as described.

2. The herein-described seam for sewed articles, comprising the fabricshaving inwardly oppositely turned edges and a binding-strip having abody portion covering the said edges, and having its edges folded aroundthe edges IOO tions of the fabrics and the bodies thereof, and providedwith a hem fold on each side, and a line of stitching passing throughthe two pieces of fabric at the folds thereof, and through boththicknesses of the binding-strip at the hem fold; substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.

EDWARD T. ALLAN.

having a body portion covering said edges, and folded around the edgesof the fabrics and lying between the inwardly-turned porl Witnesses:
